Lactonizations are important steps in many synthetic sequences. Substrate-controlled reactions that use chiral auxiliaries or chiral alkenes have already been studied in depth. This study focuses on stereoselective reagent-controlled iodolactonizations, by application of a new method that uses complexes of iodine monochloride and various donor molecules.

渗胶是许多合成序列中的重要步骤。使用手性助剂或手性烯烃的底物控制反应已得到深入研究。这项研究集中于立体选择性试剂控制的碘内酯化,方法是应用一种新方法,该方法使用一氯化碘与各种供体分子的复合物。发现(R)-1,2,3,4-四氢-1-萘胺和其他具有类似结构的胺在4-芳基-4-戊烯酸的碘环化中是有效的。对(R)-1,2,3,4-四氢-1-萘胺与XCl(X = I,H)的配合物进行了计算,以鉴定这些碘代环化反应中可能存在的反应性物种。通过使用改良的碘的SDD基集,在各种理论水平(包括B3 LYP / 6-31 + G(d,p))上进行了计算。
